JACK-STAND.

Application filed January 28, 1914.

To aZZ whom it may concern:

Be it known that I, NATHANIEL BACON, a citizen of the United States, and a resident of Sanford, in the county of York and State of Maine, have invented a. new and lmproved Jack-Stand, of which the following is a full, clear, and exact description.

My invention relates to a stand for supporting a jack in jacking up the journal boxes of car axles.

An object of my invention is to provide a stand for the indicated purpose, having means to secure and support the same on a car wheel independently of the track bed.

A further object of the invention is to provide a stand of the indicated character improved in various particulars, to the end that etliciency and convenience in operation may be promoted, as well as economy of manufacture, increased strength and simplicity of adjustment.

The invention resides particularly in features relating to the securing of the jack to the car wheel as hereinafter more particularly explained.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a jack stand showing the device applied; Fig. 2 is a vertical transverse section. Fig. 3 is a plan view of the device; and Fig. l is a detail perspective view of an adjustable prop member to engage the rim of the wheel.

It is to be understood that the illustrated example is given as a practical and preferred means for carrying my invention into effect, and it will be obvious that the invention is not strictly limited to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departing from the spirit of the invention.

Referring to the drawing, a known form of car journal box A is indicated, together with a car wheel B, a jack C and a portion of a track rail D. In constructing the illustrated example, a yoke is provided, present ing oppositely disposed, approximately horizontal arms 10 formed. with hooked ends, said ends being extended forwardly as at 11, and terminating in members 12 disposed toward each other, and spaced from the arms 10 a sufficient distance to receive the car Specification of Letters Patent.

wheel B, and embrace the same at the sides, as illustrated. Depending from the yoke is a hanger bracket 13, having a horizontal seat lfl pro ecting at the inner side in the 0pposite direction to the hooks 11, 12. In con nection with the bracket a member is provided below the yoke 10, and at the same side, to bear upon the rim 6 of the car wheel, at the inside of the latter. Said bearing member is in the form of a prop 15, which is made adjustable to vary its vertical position relatively to the yoke 10 and to the seat 14. The illustrated means for effecting the adjustment consists of a bolt 16, which extends through an oblong vertical slot 15 in the prop 15 anda wing nut 17 or equivalent on the bolt, to tighten up the latter, and firmly bind the prop against the front face of the bracket 13. The lower end 15 of the prop 15 is deflected outwardly at a clownward inclination in order that its lower edge may bear upon the rim 6 at the interior, and said bearing end is forked at its lower end, there being a slot 15 therein, as shown in Fig. 4c. The purpose of the slot is to accommodate a bolt head or nut of a car wheel in that type of car wheel in which bolts are employed at the rim.

The application of the device to a car wheel is clearly illustrated in Figs. 1 and 2, in which it will be seen that the hooks of the yoke extend around the sides of the wheel, the ends 12 of the hook engaging the flange and front of the wheel. The bearing member will be disposed so as to bear upon the member 1) of the wheel, and thus the stand is supported to properly receive the jack C beneath the journal box A. It will be observed that the stand is held supported from the wheel without any base support from the track bed and without any engagement or interference with the journal box. In this way the jack C will be positioned beneath the journal box and may be caused to lift and sustain the same while the journal bearings are removed, or replaced, as in the case of worn or overheated bearings.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

A jack stand, comprising a yoke presenting oppositely extending side arms having forward extensions at the outer ends, said extensions having terminal members disposed toward each other to hook around the flange of a car wheel, a bracket extending downwardly from the yoke, a prop on the bracket at the front beneath the yoke, and

I-' inclined downwardly and forwardly from' the bracket to engage the rim of a car wheel at the back of the latter, the terminal ends of the yoke extending forwardly beyond the prop, and a rearwardly projecting seat Copies of this patent may he obtained for five cents each. by addressing the Commissioner of Patents,
